Nocardia are gram-positive and partially acid-fast bacteria with saprophytic lives in the environment. These

groups of bacteria are able to enter the human body through traumatic inhalation and may consequently

cause Nocardiosis infections.

Case Presentation: A 32-year-old man was referred to Al-Zahra Hospital with symptoms such as fever,

gradual weight loss, and persistent coughing. First, the patient was speculated to have Tuberculosis, but

Mycobacterium tuberculosis was not isolated in any sputum samples. Ultimately, a broncho-alveolar lavage

sample was acquired from the patient and according to the patient's clinical presentation and microbial

assessments, the cause of illness was found to be Nocardia cyriacigeorgica.

Conclusion: According to this report, Nocardiosis infections may occur in immune-compromised patients

and even healthy individuals. Given the similarities between the clinical manifestations and radiological

findings of Tuberculosis and Nocardia pulmonary infections, medical laboratories should identify Nocardial

infections in suspected TB patients.
